Underground Inflation Hose Reel

Pick the UGHR when you want a complete air service unit with no assembly. Teflon-lined hose, pneumatic inflator/deflator, gauge to 35 PSI, anodized depth crimps, weighted AB-C coupling on the end. 50 m (164 ft) or 100 ft (30 m) hose options. Plug into mine air via ¼" BSP and you're ready. Working pressure 10 – 300 PSI — covers every BLASTBAG AERO and BLASTBALL spec. Best-in-class for production underground sites running daily air decks.

Pick the Inflation Assembly when you want the same kit as the UGHR but without the reel — three components pre-packaged at a common dropline length. Includes Dropline + Handheld Inflator + Weighted AB-C Coupling. Four lengths: 25 ft, 60 ft, 100 ft, and 50 m. Cheaper than the UGHR, simpler than building from parts, and field-portable.

Pick the Handheld Inflator when you're working benches without service air at the hole, or you need to reposition a bag before final inflation. Stainless steel cage, Nitto fittings, gauge to 36 PSI, rated to 200 PSI max. Inflates and deflates. Pair with any Dropline Hose and AB-C Coupling to build a portable kit.

Pick a Dropline Hose when you need a specific length not covered by the standard kits, or you're replacing the hose on an existing setup. Teflon-lined thermoplastic, designed for repeated tensile loading from lowering inflated bags. Crimps every 5 m / 10 ft tell the operator exactly how deep the bag is. Sizes: 25 ft (5 m), 60 ft (18 m), 50 m (164 ft), 100 ft (30 m). All metals are stainless steel — explosives-compatible.

Pick an Inflation Coupling when you need a replacement, a spare, or a full hose-end rebuild. The AB-C is MTi's patented snap-on connector — pushes onto the bag's air valve to inflate, pulls free under load to leave the inflated bag at depth. Two versions: AB-C Diamond Knurl (02-001, $114) is the coupling alone. The Complete Hose End Replacement (02-024, $409) is the whole end of the dropline — weight, ferrule, tail, nipple, and coupling — ready to swap onto a worn hose.

The air-operated gas bag this kit serves. Compressed air, dual-bladder construction, snap-on AB-C coupling. Two SKUs cover 2.5" to 12.25" (64 – 311 mm). Underground production, air decking, uphole capping. See the BLASTBAGS collection for full positioning, sizing, and case studies.

The wet-hole-rated air-inflated plug this kit also serves. Hermetic bladder with tire-strength nylon webbing. Three SKUs cover 2.5" to 8" (64 – 203 mm). Lower it through water, inflate to seal a breakthrough, crack, or void. See the Stemming Plugs collection for full positioning.
